⚡ At a Glance
- • Measurement Accuracy: 90mm dual-scale gauge showing 0–140 psi and 0–10 bar
- • Best for: Professional mechanics and DIY enthusiasts needing reliable fuel rail diagnostics
- • Not ideal for: Users who require electronic logging or wireless connectivity
Includes copper adapters and fittings for modern Schrader test-port systems. Pressure release valve and long drain hose allow safe recovery of fuel after tests.
Clear, reliable readings – With 90mm dual-scale gauge (0–140psi/0–10bar)
A large 90mm dial displays psi and bar at once, permitting quick reference against diagnostic targets. The analogue readout covers the full 0–140 psi range used in most automotive fuel-rail checks.
Accurate pressure readings help identify faulty pumps, regulators and leaks quickly, reducing guesswork during troubleshooting.
Safer testing and fuel recovery – With quick couplers, safety valves and drain hose
Quick coupling systems and built-in safety valves reduce the chance of accidental disconnection and uncontrolled fuel discharge. A side-mounted pressure release valve with a long drain hose allows controlled bleeding of fuel into a container.
Safer procedures minimise spill risk and make bench or roadside testing tidier and less hazardous.
Wide compatibility and fast hookup – With copper adapters for Schrader fuel-rail ports
Copper adapter and fittings match modern Schrader test ports commonly found on petrol and diesel injection systems, and standard couplings suit a range of inlet fittings. The kit is described for use on cars, trucks and motorcycles.
Rapid connection across multiple vehicle types speeds up diagnostics for mixed fleets and home garages.
